In on the road fi eld testing in medium duty trucks For 10W 30 viscosity grade only highway cycles compared to Shell ROTELLA The Environmental Protection Agency and the National Highway Traffic Safety Administration submitted their proposed Phase 2 greenhouse gas emissions and fuel economy rule for trucks and trailers to the White House Office of Management and Budget on June 3 for required regulatory review Thats the last step before the expansive rulemaking can be finalized As of press time the agencies project that OMB will complete its review quickly enough that the final rule could be published in the Federal Register as early as August A monster of a regulatory development the proposed Phase 2 rule was unveiled in June of 2015 It will cover 2021 to 2027 model year trucks and tractors and 2018 to 2027 MY trailers The big difference from the Phase 1 rule is that the Phase 2 proposal seeks to regulate trailers for the first time and set GHG limits for complete vehicles that is tractor with trailer The new rule will also set separate engine fuel efficiency standards for light medium and heavy duty vehicles The separate engine fuel efficiency GHG Phase 2 final rule could see August releasestandards would be put into play via discrete steps from the existing 2017 standards to those required for MY 2021 2024 and 2027 trucks These proposed standards require a 4 CO2 reduction from 2017 to 2027 Complying with the engine standards may entail reducing friction cutting parasitic loads using variable valve timing and making improvements in the exhaust gas recirculation combustion and fuel injection systems In addition EPA and NHTSA have projected that up to 10 of heavy duty engines could have turbo compounding and 15 of the engines could have waste heat recovery systems by 2027 to meet the strictest standard The Phase 2 proposal also addresses natural gas vehicles and engines including emissions from the crankcase and liquefied natural gas LNG boil off two of the largest sources of on vehicle methane emissions And the proposed rule affects glider kits These kits would be subject to GHG limits and would require starting in 2018 that engines used in them meet the same standards as new vehicles PHOTO ISTOCKPHOTO COM FRENTUSHA
